ESO Advent Calendar - Puzzles

This swap is part of a cooperative project by ESO group officers/founders. Even if they are hosted by different people they belong to the same series of swaps. This is swap 7 out of 8.

In each of these swaps you will send and receive six gifts - so in order to have a full advent calendar, you need to join four of these swaps. You do not need to join all advent calendar swaps, though - just pick the four themes you like best. As a result, you should have 24 little gifts to open through all of December! Of course it is also okay to join just one of these swaps if you're cool with opening something only every four days. ;-)

For this swap, you will have one partner whom you'll send six different (logic) puzzles. Each puzzle should be wrapped individually - in an envelope (do decorate it a bit if it's plain white), wrapping paper, or any other way you can think of, as long as it keeps the exact content a surprise until opening. Put your six gifts into an envelope and send them to your partner. Don't forget to add a note which swap it is for.

The puzzles don't have to be Christmas themed but if you want them to be, it is of course allowed to send Christmas themed items. Puzzles may be of same or similar type (all Sudokus; or all grid puzzles "who lives in which house and drinks what warm drink" kind) or each of a totally different kind, they just shouldn't be the very same puzzle repeated. Puzzles could be printed off internet, cut from a magazine, or - why not! - made all by yourself. Please do send only one or two easy or medium puzzle per day - just a little bit of fun exercise while drinking morning coffee, not a duty to spend the day solving puzzles!

Puzzles are senders choice, but do look at your partner's profile to avoid major dislikes.
